Resettable Non-Interactive Zero-Knowledge: Attacks and Defenses
Nahid Roustaeifar
As zero-knowledge proofs are increasingly deployed in real-world systems, they face new security threats beyond traditional theoretical guarantees. One important threat is resetting attacks, where an adversary exploits side-channel vulnerabilities or fault injection to manipulate a prover's randomness generation. While resettable zero-knowledge has been extensively studied for interactive protocols, it remains unclear whether modern non-interactive arguments (e.g., zkSNARKs) are secure against r
